Shure ADX2/B58 — Axient Digital Handheld Wireless Transmitter (X55)
ADX2/B58 Overview
The Shure ADX2/B58 is a professional handheld wireless transmitter designed for the Axient Digital platform, operating in the X55 band (941-960 MHz). Built around the proven Beta 58A supercardioid dynamic cartridge, it delivers the vocal clarity and off-axis rejection that engineers rely on in demanding live and broadcast environments. With a tuning range of up to 184 MHz, the ADX2/B58 provides the spectrum flexibility needed to navigate congested RF environments at large-scale productions, houses of worship, and touring applications. It is purpose-built for audio engineers and system integrators who require reliable, remotely manageable wireless performance.
The transmitter’s all-metal construction and black finish offer durability suited to touring and rental inventory, while its advanced rechargeability and ShowLink remote control integration streamline both setup and live operation from the front-of-house position.
